Jersey,
The shop where I shoot and work on my bow has this vise and the various levels. I have used them many times. I see they say it is improved for '04. I am not familiar with this new one. The one I use is a year or two old, maybe. It seems to work very well on a variety of bows. My bow is of the parallel limb design, and the vise works fine in either the horizontal or vertical position. It allows for fairly precise leveling of the bow during setup. In the horizontal position, it makes it very easy to install peep sights, or do any serving work. All in all, I have been pleased with these devices.
